Question and Answers

Q:

safety switch 917273811 Craftsman Tractor

A:

Thanks for the inquiry and for being a valued member. 

I am sorry to hear of the issue you're having with the tractor. I know how frustrating that is.

This type of issue is typically caused by one of the tractor's safety switches. There are three safety switches on the unit. There is the seat switch, blade engagement interlock switch, and the brake/clutch interlock switch. 

I would start by cleaning the contacts and making sure the connectors are firmly secured. If that doesn't help, you will need to test the switches for continuity with a meter. To help you do so, I have linked a short video below that you can watch.

Q:

Fuel tank or Stem 917273811

A:

Thanks for the inquiry and for being a valued member.

This fuel pump operates off of a vacuum. There is a vacuum line on the pump itself that will usually connect to the valve cover or the dipstick tube. Make sure the vacuum line is securly connects and bend the line to check for cracking. If the line is not securely connected, or is cracked in any way, the pump will not operate. 

If that doesn't appear to be the case, you will need to take off the fuel lines and blow through the fuel fitting to clear any varnish or clogs. It sounds like a vacuum issue with the pump however.

Q:

mdl 917273811 cranks and runs then shuts off 917273811

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the tractor. I know how frustrating that is.

It definitely sounds like a safety switch issue. Outside of the clutch/brake switch and blade engagement switch, there is also the seat switch. However, the issue may not be with the switch itself. It could be the power is dropping before the switch, and it could be a wiring issue. You could have an open or shorting wire. I would clean the contacts, check the connections to make sure they are secure on all three switches, and if you have a meter, verify they have power going in and out of the switch wires.
